The examples given on your side were not relevant. You talked about Egypt, which even you admit is not an example of us arming anybody. Steven talked about either groups that pre-date the existence of the U.S. and therefore cannot be examples of the U.S. arming them or he talked about groups that the U.S. flatly did not arm.
If you feel insulted, I suggest that in the future when somebody asks you to provide a historical example of a historical claim that you have made, you really ought to find an response other than a condescending remark about how the other person needs to go read some history. If you can't back up your own claims about history, you have no business implying anybody else has less knowledge on the topic than you do.
